FAQs on Mind Map: Structure of Atom - Chemistry Class 11 - NEET

1. What are the main components of an atom?
Ans. The main components of an atom are protons, neutrons, and electrons. Protons and neutrons are found in the nucleus at the center of the atom, while electrons orbit the nucleus in various energy levels.
2. How do protons and neutrons differ from electrons in terms of charge and mass?
Ans. Protons have a positive charge and a significant mass, making them heavier than electrons. Neutrons have no charge (neutral) and a mass similar to that of protons. In contrast, electrons have a negative charge and a much smaller mass compared to protons and neutrons.
3. What is the significance of the atomic number and mass number in an atom?
Ans. The atomic number of an atom is the number of protons in the nucleus and determines the element's identity. The mass number is the total number of protons and neutrons in the nucleus and provides information about the atom's overall mass.
4. How does the arrangement of electrons in an atom affect its chemical properties?
Ans. The arrangement of electrons, especially in the outermost shell (valence electrons), determines how an atom interacts with others. Atoms with similar electron configurations often exhibit similar chemical properties and reactivity.
5. What role do isotopes play in the understanding of atomic structure?
Ans. Isotopes are variants of the same element that have the same number of protons but different numbers of neutrons. They help in understanding atomic structure by demonstrating how variations in neutron count can affect an element's mass and stability, as well as its applications in dating and medical imaging.
